Lees Ferry on the Colorado River below Glen Canyon Dam is a world-famous rainbow trout fishery. But in recent years a different nonnative fish, the brown trout, has started to grow in numbers. The brown trout is a predatory fish that gobbles up not only the rainbows but also endangered native species in the Grand Canyon. Now, state and federal wildlife agencies have come up with a plan to reduce their numbers. They’re paying people to go fishing. Starting today, anglers can earn 25 dollars a head for catching and harvesting brown trout. KNAU’s Melissa Sevigny spoke with Ken Hyde, chief of science at Glen Canyon National Recreation Area, about the new incentive program.


In autumn swarms of flying insects cloud the skies on the lower Colorado River near Bullhead City. Caddisflies are a nuisance to recreationists who want to boat, swim or fish on the river. So city officials have started an unprecedented experiment to get rid of them. They recently tweaked the operation of Davis Dam to lower the river’s level and try to kill off the bugs. But just three hundred miles upriver another first-of-its-kind experiment is happening at Glen Canyon Dam, with the goal of SAVING caddisflies, not killing them. KNAU’s Melissa Sevigny reports on how the Southwest’s largest river ended up in a tug-of-war over a tiny bug.

A nonprofit environmental group has negotiated a truce with federal agencies after a long-running lawsuit over the threatened Mexican Spotted Owl. WildEarth Guardians sued the U.S. Forest Service and U.S. Fish and Wildlife Service in 2013, saying the agencies failed to monitor owl populations in Southwestern forests and assess the effects of thinning and burning. The new agreement promises to remedy that on all eleven national forests in Arizona and New Mexico. KNAU’s Melissa Sevigny spoke with John Horning, executive director of WildEarth Guardians.

The Arizona Game and Fish Department still is seeking those responsible for the illegal poaching of a bull elk last month. The agency announced Tuesday that the reward for information leading to an arrest in the case has been increased to $6,500. Game and Fish officials say the elk was killed between the evening of Sept. 15 and the morning of Sept. 17 southeast of Pinedale, which is in northeastern Arizona.

The elk’s antlers were removed and the meat was left to waste.
